BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to photosynthesis, more particularly to a photosynthetic device with a microfluid chamber and a method for causing photosynthesis in the microfluid chamber.

2. The Prior Arts

Owing to increase in concentration of so-called greenhouse gases (like carbon dioxide (CO₂), methan (CH₄) and nitrous oxide (N₂O)) produced by human activity and industry results in rising of the global temperature, which in turn, causes an increase evapotranspiration, thereby altering the heat balance system and changing the distribution of rainfall. That is causing the rainfall or floods in areas of drought originally, and the floods or rainfall in places where there is drought originally. Regarding the production of food crops, not only the temperature changes, so do the crop seasons, which is in need of moisture can not get water and/or vice versa, leading to significantly reducing the world crop production.

In addition to causing climate change, water crisis, food scarcity also result due to interactive effects. According to the UN assessment of global land resources, nearly a quarter of the world's agricultural land is affected or degraded seriously, but the world's population continues to grow. In order to feed all of humanity sufficiently, an increase of 70 percent of food production should be increased by 2050 the latest year or else starvation will be prevalent in the near future.

As such, the real solution for the currently existing problems resides in how to solve the food shortage and how to effectively reduce emission of greenhouse gases lie ahead of us.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification. The drawings illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.

FIG. 1 is a schematic diagram illustrating the first embodiment of a photosynthetic device of the present invention. The photosynthetic device of the present invention includes a main body 100 and a light source 105. The main body 100 defines a microfluid chamber for causing photosynthesis therein and preferably has a volume of 3.5 cm*3.5 cm*0.7 cm, but the size thereof should not be limited only thereto. The microfluid chamber is constituted by at least one communication room 101, a plurality of micro channels 102 respectively and spatially communicated with the communication room 101, at least one micro injection duct 103 spatially communicated with the communication room 101, and a plurality of filter plugs 104 spatially connected to the micro channels 102 respectively and the micro injection duct 103 at free ends thereof in order to filter fluid backflow in the micro channels 102 and the micro injection duct 103. The light source 105 is capable of radiating one of the communication room 101, the plurality of micro channels 102 and the micro injection duct 103. In this embodiment, the communication room 101, the micro channels 102 and the micro injection duct 103 are fabricated from transparent material, such as glass. The communication room 101 is circular in cross section and has a diameter of 2 cm, but the size should not be limited only thereto. Each of the micro channels 102 and the micro injection duct 103 has a first end connected spatially with the communication room 101 while the second ends of the micro channels 102 and the micro injection duct 103 are provided with the filter plugs 104 respectively such that photosynthesis is resulted once chloroplasts and normal saline solution are injected into one of the communication room 101, the micro channels 102 and the micro injection duct 103. Preferably, the micro channels 102 and the micro injection duct 103 are rotatable relative to the communication room 101 so as to evenly distribute the chloroplasts 106 within the channels and the injection duct in order to achieve the effective photosynthesis. Any connection means can be employed so long as it permits rotation of the micro channels 102 and the micro injection duct 103 relative to the communication room 101.

In this embodiment, the normal saline solution is injected ceaselessly into the communication room 101 and the micro channels 102 via the micro injection duct 103 while the filter plugs 104 prevent the chloroplasts from spilling out therefrom. Under this condition, chloroplasts within the normal saline solution are evenly and uniformly distributed so as to achieve the effective photosynthesis. As shown in FIG. 1, the filter plugs 104 are located outside the main body 100.

FIG. 2 is a schematic diagram illustrating the second embodiment of the photosynthetic device of the present invention;

The second embodiment is generally identical to the first embodiment in structure, except that the second embodiment of the photosynthetic device of the present invention further includes an extra communication room 201 and a connection micro channel 207 interconnecting spatially the extra communication room 201 with the communication room 201. Preferably, the connection micro channel 207 is rotatable relative to the extra communication room 201 and the communication room 201 so as to distribute the chloroplasts 206 evenly and uniformly within the connection micro channel 207 in order to achieve the effective photosynthesis once chloroplasts and normal saline solution are ceaselessly injected via the micro injection duct 203. Since mounting and functions of the filter plugs 204 are identical to the first embodiment, a detailed description thereof is omitted for the sake of brevity. An important note is that only a single micro injection duct 203 is used in the second embodiment, however the number should not be limited only thereto.

FIG. 3 shows a block diagram illustrating the steps constituting a method for causing photosynthesis via a photosynthetic device of the present invention.

The method for causing photosynthesis via a photosynthetic device, wherein, the photosynthetic device includes a main body defining a microfluid chamber for causing photosynthesis therein. The method accordingly includes the steps: S31 injecting chloroplasts and normal saline solution into a microfluid chamber for causing photosynthesis therein, the microfluid chamber is constituted by a communication room 206, a plurality of the micro channels 202 respectively and spatially communicated with the communication room 201, at least one micro injection duct 203 spatially communicated with the communication room 201, and a plurality of filter plugs 204 spatially connected to the micro channels 202 respectively and the micro injection duct 203 at free ends thereof in order to filter fluid backflow in the micro channels 202 and the micro injection duct 203. Preferably, the micro channels 202 and the micro injection duct 203 are rotatable relative to the communication room 201. In step S32, chloroplasts and normal saline solution are injected ceaselessly via the micro injection duct. In step S33, one of the micro channels is radiated by a light source (such as sunlight) in order to cause photosynthesis within the micro channel.

FIG. 4 is a graph illustrating the relation between glucose amount vs photosynthesizing time carried out according to the photosynthesizing method of the present invention.

As illustrated in FIG. 1, the normal saline solution is injected ceaselessly into the communication room 101 and the micro channels 102 via the micro injection duct 103 so as to cause photosynthesis therein and after reaction glucose spills out from the filter plugs 104. As shown in FIG. 4, after one hour of photosynthesis, 0.25 g/ml of glucose is obtained. After two hours of photosynthesis, 0.5 g/ml of glucose is obtained while 2.0 g/ml of glucose is obtained after 6 hours of photosynthesis.

One aspect to note is that the photosynthesis is caused not in the green plant, but rather in the micro fluid chamber of the present invention as long as we can extract chloroplasts from plants and using the same in the photosynthetic device of the present invention so as to produce the glucose in combination with water and sunlight. In other words, emission of carbon dioxide can be reduced when the photosynthetic device of the present invention is implemented.
